(999+1002*1000)/(1001*1002-3)(999+1002*1000)/(1001*1002-3)(999+1002*1000)/(1001*1002-3)(999+1002*100
(999+1002*1000)/(1001*1002-3)
(999+1002*1000)/(1001*1002-3)
(999+1002*1000)/(1001*1002-3)
(999+1002*1000)/(1001*1002-3)
= (999+1002*1000) / {(1000+1)*1002-3}
= (999+1002*1000) / {1000*1002 + 1002 - 3}
= (999+1002*1000) / {1000*1002 + 999 }
= 1
(999+1002*1000)/(1001*1002-3)
999*999-1002*998=( )
999^2-1002*998
999²-1002*998
999²-1002*998
